Why didn't the main character stay in one spot and keep upgrading

Why didn't the main character stay in one spot and keep upgrading it will infinitely improve his soul power and no one can mess with him? THen afterward he can leave the forest after killing the bandit.Not only that he can buy gems infinitely and keep upgrading them to +13 and +14 then it will immensely improve his agility and strength.Also why didnt he buy a glove, by using a glove a glove as a weapon he can hide all the rings he wear, and when he use his palm it will be soooooo much stronger, everytime he does a 9 palm strike, the +12 effect will activate this will be insane. Buy the boots and upgrade his speed so he can fled faster.I dont understand why the MC didn't exploit all these easily exploitable equipment.He can be so overpower.

He is already doing that at this moment in the translated chapters. But he can't do that everywhere.

1) he can't buy and sell equipment unnoticed.2) he can't sell his upgraded equipment.3) his soul power only improves if he'd drained it with upgrading. But the last few translated chapters already explained it's very dangerous to randomly pass out. He needs to be in a safe place.

Na he has a point. At the beginning he could have stayed in some cave in who knows the fuck where and upgrade pebbles. It does not have to be useful just has to waste soul power. So in some cave in bumbelfuck where no one ever comes across him just upping soul power before doing anything else would sound logical so there is no way Mc would ever do it lol.

Befor becoming a soul sprtie he uses the upgrade technique to drasticaly increase his soulforce. But once he became a soul sprite he nearly exploded, because he wasn't able to control his powers. After that he seldom empties his soulforce while upgrading
